 2. Discussion Topics  
 
2.1 Opening remarks from the Chair and RPMs  
• As noted in the email sent to the review team on July 9, 2021, the new  
targeted action due date (ADD) for the BLA is September 15, 2021.  
• Prior to the meeting, the Chair requested that the review committee provide 
projected dates for  the completion of their  discipline  review s. Please see 
Table 3, included at the end of this document , for a list of  review activities and 
projected target completion dates  (Appendix).  
• The RPMs summarized the IRs and Amendments to the BLA to date (please 
see details at end of document).  
 
2.2 Review of milestones and internal/projected target dates  
• The Filing Letter is targeted to be issued and sent to the Applicant on July 16, 
2021. 
• A meeting to discuss the non- proprietary product name has been scheduled 
for July 26, 2021.  
 
2.3 Status update (including any major concerns that have been identified so far) from each member of the review committee  
 
2.3.1 Clinical (Susan Wollersheim and Ann Schwartz):  
• The clinical reviewer s have been working with the statistical reviewers to 
determine the preferred terms for AESIs in the VAERS datasets  so that 
they correlate with safety analysis in clinical trials . They are currently  
ensuring that no IRs will be required for the unblinded periods  of the 
clinical trials.  Additionally, IRs regarding efficacy of the vaccine are being 
drafted regarding the inclusion of  data from subjects  12-15 years of age 
and to provide shell tables to the Applicant for safety and efficacy . 
 2.3.2 CMC (Xiao Wang):  
• The CMC reviewer sta ted that the r eview of the drug substance is close 
to be finished which will then be follo wed by review of the drug product.  
There were  no specific issues that needed to be discussed with the 
group during the meeting. 
 2.3.3 DBSQC (Hsiaoling Wang, Emnet Yitbarek, Karla Garcia, Anil Choudhary, Esmeralda Alvarado and Marie Anderson):   
• The DBSQC reviewers provided updates that the reagents  and lots for 
testing were received last week.  IRs regarding the lot release protocol 
templates as well as the number of freeze/thaws allowed for the drug substance will be finalized for sending to the Applicant soon. 
• It is not certain at this time that t he in-support testing (  
 of DS) will be complete by the target action date since

STN 1 25742/0  Monthly Meeting date: July  15, 2021

 some of the reagents required for testing have been backordered and 
the new equipment need to be installed. 
 
2.3.4 Toxicology (Nabil Al -Humadi):  
• The toxicology reviewer w as unable to attend the meeting, but there 
were no issues to be discussed regarding the progress of the toxicology 
review.  
 2.3.5 Statistics (Lei Huang , Ye Yang and Xinyu Tang): 
• The statistical reviewer noted that his review  is ongoing and they are 
targeting completion of the stats  review memo at the same time as the 
completion of the clinical review.  To help with the review, two new 
statistical reviewers have been added to the review committee: Ye Yang will review safety data while Xinyu Tang will be responsible for non -
clinical data.  Xinyu Tang asked to contact her  if any of the discipline 
reviewers need non- clinical stats support.    
 2.3.6 Epidemiology/Pharmacovigilance (Deborah Thompson) : 
• The reviewer noted that  a pregnancy registry protocol  was submitted to 
the BLA which she is reviewing to determine if it will be a PMC. 
 2.3.7 DMPQ (Kathleen Jones, Laura Fontan, Gregory Price, Zhongren Wu, Donald Ertel, Ekaterina Allen, Cheryl Hulme and Iryna Zubkova):  
• The DMPQ reviewers  are finalizing an IR for the first round of comments 
to send to the Applicant next week. The Andover inspections will take place from July 19- 23 and the Puurs inspections occurred from June 23-
July 2.  Pending final management review, the waiver for inspec tions of 
the Kalamazoo site will be closed next week.  
• Until all facilities have been inspected, a firm date for the completion of 
DMPQ’s review cannot be provided.  
 
2.3.8 BiMO (Haecin Chun):  
• The BIMO reviewers had no issues to share with the review committee. 
BIMO inspections were previously  conducted for Protocol C4590001. 
Due to the COVID -19 pandemic restrictions, no foreign study sites were 
selected. On- site inspections were conducted for a total of nine (9) 
domes tic study sites and the final classification of all nine inspections 
were No Action Indicated (NAI).  No significant information was gathered 
from the inspections that would preclude approval of the BLA.  
• BIMO noted that the data integrity component of these nine inspections 
was missing. However, since no study conduct issues were identified during inspections, BIMO does not believe that the lack of the data 
integrity component is a concern.  
• BIMO wanted to make the team  aware of the previous BIMO inspec tion 
history of Dr. Michael Levin (Study Site# 1036), who had participated in 
FDA-CBER-2021-5683-1024847
STN 1 25742/0  Monthly Meeting date: July  15, 2021

 the study of Protocol C4590001. His study site was inspected last 
November for a Moderna COVID -19 Vaccine clinical trial. At the end of 
the inspection, a form 483 was issued. CBE R classified it as OAI (Official 
Action Indicated) and an untitled letter was issued to Dr. Levin.  
 
2.3.9 APLB (Oluchi Elekwachi):  
• The APLB reviewer reminded the  review committee that  priority name 
review for the submission was  completed and comments are being 
drafted. If additional safety changes  are made, APLB will make an 
addendum.   
 2.3.10 Container Labeling (Daphne Stewart):  
• The reviewer noted that no major issued have been identified and minor 
IRs will be sent out for the labels later.  
 
 
2.4 Additional  Discussion Item : Post-authorization Effectiveness Data  
• N o post -authorization effectiveness data were submitted to the BLA . 
However, there have been numerous studies published to date on the real -
world evidence (RWE) from the post-authorization use of Pfizer -BioNTech  
COVID- 19 Vaccine. The review team and managers discussed the best way 
to include the RWE data into the clinical  review memo, if at all.   
• The clinical reviewer and others noted that  RWE would be difficult to capture 
in the review memo due to the high volume of data that is being published; 
any information included in the memo would be quickly outdated. As a 
compromise, a summary could be included in the review memo stating 
whether  RWE data affect the conclusions from our review and whether they 
are or are not contradictory to what was observed in the clinical trials for effectiveness.
